Submit Gasless Transaction

Submits signed executions obtained from a gasless GET /getAction response for relay broadcast. The backend validates each signature, simulates the transactions, then broadcasts them via the configured relay provider.

Call this endpoint only when executionsType is GASLESS in the getAction response. Sign all items in the executions array in order before submitting.
